The 2210-kg anvil A of the drop forge is mounted on a nest of heavy coil springs having a combined stiffness of 3.6(106) N/m. The 550-kg hammer B falls 430 mm from rest and strikes the anvil, which suffers a maximum downward deflection of 18 mm from its equilibrium position. Determine the height h of rebound of the hammer and the coefficient of restitution e which applies.

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)
